Specifications

• Cutoff Voltage: as low as possible so the heli will not fall out of the sky. If you are using lithi-
um polymer batteries, you will need to be careful not to drain the batteries beyond the re-
commended minimum voltage.
• Current Limiting: insensitive
• Brake: disabled - so we don't strip the main gear when the motor spools down.
• Throttle Type: fixed endpoint
• Timing Advance: depends on motor, choose standard if unknown
• Cutoff: soft
• Soft start: Choose fast start
• PWM Switching Rate: depends on motor, but 11 khz is fine for most tail motors
13.4.2.3. Schulze ESC parameters for MAIN motor
Note
0 = switch in LEFT position with label readable
1 = switch in RIGHT position with label readable
1. Switch 1: 0 - aircraft mode
2. Switch 2: 1 - helicopter mode
3. Switch 3:
FP helis: 0 - normal speed controller
CP helis: 1 - governor mode
4. Switch 4: 0 - high rpm mode
5. Switch 5: 1 - soft timing
6. Switch 6: Set to 1 (19 khz) for coreless (non-cogging) motors; for other motors, set to 0
(9khz)
For other ESCs, set the parameters using the above parameters as a general guide.
If you have a programmable ESC which is programmed using beeps then you should carefully
watch the tail servo when the ESC beeps. If your tail servo wiggles every time the ESC beeps,
then your gyro or gyro wires are too close to the ESC.
13.4.3. Transmitter throttle setup
1. Remove the MAIN BLADES from the helicopter
2. Secure the helicopter so it cannot move.
For a nonmicro heli, put a wooden beam or two-by-four through the skids and place a
brick or other heavy object on each end of the beam. For a micro heli, put a piece of wood
